DANGER
Thermic overload protection:
Standard equipment with PTC-thermistor 130°C from housing size 170 up-
wards.
For smaller vibrators: available on request as initial equipment.
If the vibrator is operated in areas with potentially explosive dust (zone
22), it is compulsory to connect the PTC-thermistor. This regulation does
not apply for units without a PTC-thermistor.
DANGER
Only suitable, flexible supply cables must be used
for connecting the vibrators.
The conductors in the supply cable for the connec-
tion of the vibrators to the mains must be tempera-
ture-resistant and have a sufficiently large cross-
section, which is adapted to the cable length used.
The temperature resistance of the cables depends
on the maximum surface temperature stated on the
type plate.
IMPORTANT
When selecting the connection cables, consider that the cables are mechanical-
ly stressed by vibration.
Recommended cable types for mains operation at 400 V, in potentially non-
explosive atmosphere: rubber hose line H07 RN-F or oil flex cable 110 CY.
For other voltages or other ambient conditions, the cables must be adapted to
the respective conditions and designed accordingly.
DANGER
The terminal box cover may not be opened in a po-
tentially explosive atmosphere or when voltage is
applied.
If the terminal box cover or unbalance covers are
open, check the condition and correct positioning of
the seals. Damaged seals must be replaced imme-
diately.
Cable temperature near
the cable gland: 120 °C
DANGER
The electrical cables must be carefully laid. Care must be taken to ensure that
the cables are not chafed through by vibrating parts.
The correct condition of the electrical cables with their plugs must be checked at
regular intervals (usually every six months). Detected errors are to be eliminat-
ed immediately. Protect the cable from high temperatures, lubricants and sharp
edges.
DANGER
Tighten terminal plate nuts with pre-
scribed torque. Remember to put the
safety washer between the ring and
the nut and the vibration-damping in-
sert back.
M 4  1,2 Nm
M 5  2,0 Nm
M 6  3,0 Nm
M 8  6,5 Nm
M 10 13,5 Nm
IMPORTANT
The wire ends must be fitted with insu-
lated cable lugs, in order to prevent
the strands from splaying. The maxi-
mum size of the cable lugs can be
found in the following table:
Set screw M4 max. AWG 18
Set screw M5 max. AWG 16
Set screw M6 max. AWG 12
Set screw M8 max. AWG 12
